7 Application filed January 10, 1914. Serial No. 811,339.

To all whom it may concern:

Be it known that I, HERMANN TONN, a citizen of the United States,residing in the city of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Metal BeltLacing,of which the following is a specification.

The object of my invention is to provide a belt lacing which is at oncesimple, effective, durable, inexpensive and easy to apply.

In the drawings, Figure 1. is a perspective view of a piece of myimproved belt lacing in its preferred form as it appears before it isapplied to a belt; Fig. 2. is a top plan view of the lacing shown inFig. 1.; Fig. 3 is a side elevation of such lacing; Fig. 1 is aside-elevation of such lacing applied to a belt; Fig. 5 is a top planview of the lacing and belt shown in Fig. 4; Fig. 6 is a bottom view ofthe lacing and belt shown in Fig. 4; Fig. 7 is a side elevation of amodified form of my lacing, used especially in the case of round belts;Fig. 8 is a sectional elevation, along line 88 in Fig. 7, of the lacingshown in Fig. 7; Fig. 9 is a side elevation of such lacing applied to abelt; and Fig. 10 is a perspective view of the lacing shown in Fig. 7,provided with a modified form of hooks.

Referring to the drawings, my lacing consists preferably of a metalstamping, formed, as shown in Figs. 1 to 3, of a central plate 20 withhooks 21 thereto attached. These hooks are bent over from both the upperand lower edges of plate 20, alternately projecting to the right and tothe left from each edge, and preferably arranged so that for each hookbent over to one side, another hook is bent over to the opposite side,in the same vertical plane, from the opposite edge of plate 20. Hooks 21are bent so as to leave open, between their points, 0 enings 22 intowhich ends 23 of belt 24 may e projected so as to be brought in contact,from opposite sides, with plate 20. When this has been done, hooks 21may readily be hammered or pressed into ends 23, thereby fastenin themtogether as shown in Figs. 4 to 6. lhe shanks of the upper and lowerhooks, respectively, on each side of plate 20 are preferably made ofdifferent length in order that the points of the hooks may not allpenetrate ends 23 at the same distance from plate 20.

The form of lacing shown in Figs. 7 to 9, used especially with roundbelts, has the special advantage that it may easily be made so as togrip the belt ends from three, four, 7

or more sides. Its central plate 20 is preferably made round, and ofslightly smaller diameter than the belt on which it is to be used, andhooks 29 project from it alternately to one side and to the other, insuch manner that each of the belt ends may be engaged by two, three ormore hooks 29 driven into it from substantially opposite directions. Thelacing illustrated by Fig. 10 is substantially the same as that shown inFigs. 7 to 9, except that the hooks are formed in a different way, andthat each prong is provided with two hooks. This form of hooks is ofparticular advantage with round belts because it is difficult to drivesingle hooks straight into a round belt.

Further modifications of my lacing may easily be conceived. All such areintended to be covered, if within the purview of my claims.

I claim 1. As a new article of manufacture, a metal belt lacingcomprising a plate adapted to be interposed between the belt ends to bejoined together so as to face the butts of such belt ends with its flatsurfaces, and hooks integral with said flat plate and projectingtherefrom in opposite directions so as to be adapted to grip both ofsaid belt ends by being driven into them from substantially oppositedirections.

2. As a new article of manufacture, a metal belt lacing comprising aplate, adapted to be interposed between the belt ends to be joinedtogether so as to face the butts of such belt ends with its fiatsurfaces, and hooksprojecting from the edges of such plate alternatelyto one side and to the other, and adapted to grip an end of a belt oneach side of the plate by being driven into it.

3. As a new article of manufacture, a provided With two prongs adaptedto enter metal belt lacing comprising a connecting said belt side byside. body, and hooks projecting from such body HERMANN TONN. inopposite directions so as to be adapted to Witnesses 5 grip both ends ofa belt from substantially WM. STAHLHEBEN,

opposite directions, each of said hooks being FRANK D. GASSMIRE.
